Specification of Letters Patent.

Patented Jan. 16, 1906.

Application filed July 12, 1905. Serial N 0. 269,422.

Be it known that I, ADoLF SwoBonA, a subject of the Emperor of Austria-Hungary, re-

siding at Vienna, Austria-Hungary, have in-.

, vented-a certain new and useful Improvement in Matches, of which the following is a speci- This invention relates i nitlng compounds for matches of al kinds, wax

matches and others,) these compounds distinguishing from other compounds of similar kind in asfar as the same are free from poisonous phosphorus and sulfur and containing besides other-known igniting materials a certain amount of substances that give to the compounds qualities hitherto unknown.

'The heads of all matches now in use the ignition of. which is required to take place upon any rubbing-surface whatever contain the constituent parts necessary for ignition, viz: chlorate of potassium, amorphous hos phorus, and sulfur, in a mixture to whic are added, according to prescriptions, some other substances serving principally as filling or bindin materials. Experience has shown that al these igniting compounds do not turn out well in practice, because they are subject to the same defects, and the danger of exploding during manufacture of such igniting com pounds has not yet been entirely prevented.

Now I have found that when adding .a mixture consisting of three parts, of weight, of finely-powdered cork, fifteen parts, of weight,

of iron minium, twenty-three parts, of weight,

parts, of weight, of water to igniting compounds alrea y known, the constituent parts and proportions of which are indicated in the following example, an igniting compound free of poisonous phos horns and sulfur may be obtained in the co (1 without any danger and without development of injurious vapors. The resultin compound allows the manufacture of matdli sulfured wood splits or o wax sticks) that are ignited when rubbed upon any rubbingsnrf ce whatever.

The original compoundused for makingv the imroved igniting compound consists of about fifty-seven parts, of weight, of chlorate of potassium, about seven parts, of weight, of

to a composition used for the manufacture of im rove es of all kinds (of parafiined or 7 red chromate potassium, (K CrO about seven parts, of weight, of amorphous phosphorus, about fifteen parts, of weight, ofpowdered glass, and about thirty parts, ofweight, of gum-arabic dissolved in about forty parts, 7

of weight, of water.

By means of the composition before specified an improved igniting compound may be manufactured in the cold, preferably in the following manner: Thirty parts, of weight, of gum-arabic are dissolved in forty 'parts,'of weight, of water. To this solution are added fifty-seven parts, of Weight, of finely-powdered chlorate of potassium. After'suspen- 'sion of the chlorate of potassium seven parts, of weight, of chromate of potassium, seven parts, of weight, of amorphous phosphorus,

and fifteen parts, of weight, of powdered glass are poured into this solution, and the whole is intimately mixed by stirring. A paste is then prepared of three parts, of weight, of powdered cork, fifteen parts, of weight, of iron minium, and twenty-three parts, of Weight, of 'flour,'the whole mixed with forty parts, of weight, of water. This paste is added to the liquid mixture before described, and

the whole mass is again intimately mixed.-

The improved igniting compound permits of manufacturing of matches without a pre-' ceding drying, preheating, or parailining of the splints, and besides this it offers the following very important advantages: Ignition of the carrier of the igniting compoundas, for example, splints orwax sticksis perfectly as sured,'and every danger of exploding during of the several constituent parts of the paste viz., of the cork, iron minium, and flouris the following: The powdered cork does not only prevent depositing of the constituents of the igniting compound, but, contrary to powdered wood, it p ev nts a sudden flaring up of the igniting compound an makes the latter soft'and supple. The flour makes he compoundconsistent to such an extent as re- .quired for the dipping process. The 11011 haveprolonged thread-like ends. 7 The finished headof the matches may be covered with a layer of grease, protectin same against all atmospheric influences and preventing self-ignition during manufacture or transport. v I

What I claim, anddesire to secure by Letters' Patent, is-

1'. The compo powdered cor iron minium,-flour and water substantially as described and for the purposes e'cified.

2. he herein-described composition of matter as additional matter to igniting c0m poundsfor' matches of all kinds consisting of three parts of weight of powdered cork, fifteen parts of Weight of iron minium, twentysition of matter consisting of three parts of weight of flour and forty parts of Weight of Water, substantially as described. 3. The herein described" composition of minium, flour and water in'coinbinati'o'n with an igniting compound for matches conslstlng potassium, seven parts of weight of red chromate of potassium, seven parts of weight of amorphous phosphorus, fifteen parts of Weight of powdered glass, thirty parts of weight'of gum-'ara'bic' and forty parts of weight of water, substantially as described.
